Definitions
- This invention concerns absorbent articles having a raised elasticized barrier and pocket for containing exudates.
- Disposable absorbent garments and the manufacture of such garments, are well known in the art.
- Disposable absorbent garments typically include a moisture-impervious backing sheet, an absorbent pad, and a body-contacting liner sheet.
- such garments also include elasticized regions for securing the garment about the waist and legs of a wearer. These elasticized regions have been produced from varying patterns of the elastic members. Serpentine elasticized areas have been used to form elasticized leg openings.
- This invention is directed to an absorbent article that includes a pocket for containing exudates which is formed by providing an elasticized barrier region of the liner sheet.
- the absorbent article does not require, but may include, an inner layer.
- Prior art garments that included a pocket typically required an inner layer in addition to a liner sheet.
- the article of the present invention therefore provides savings in terms of material costs.
- the article comprises a moisture-impervious backing layer, a liner sheet, and an absorbent core layer that is positioned between the liner sheet and the backing layer.
- Elasticized inner-layer barrier means also are included to define a pocket for receiving exudates.
- the barrier means are located substantially in the crotch region of the absorbent article.
- the elasticized barrier means may comprise an elasticized portion of the liner sheet.
- the elasticized barrier means may comprise elastic members joined only to the liner sheet in regions adjacent to the absorbent core.
- the elastic members are not attached to the pad or to the backing sheet in such regions.
- the elastic members may have adhesive on both surfaces, so that they attach to both the liner sheet and backing sheet.
- the formation of the exudate pocket is facilitated by having the elastic members attached only to the liner sheet in regions adjacent the pad and in the crotch of the article.
- the article fits snugly around the legs of a person wearing the article if the elastic members are attached to both the liner sheet and backing sheet in those regions of the article that define leg openings.
- the liner sheet is not joined to the backing layer or the pad at regions adjacent the elastic members.
- the article also may use elastic means to define both leg gathers and a raised elasticized barrier, the barrier defining a pocket region to receive exudates.
- the elastic means are attached to the liner sheet, such as by an adhesive.
- the liner sheet is not bonded to the absorbent core and the backing sheet at regions of the liner sheet adjacent to the edges of the elastic means.
- the liner sheet is not joined to the absorbent core or backing layer from at least about 5 mm to about 20 mm adjacent the first and second edges of the elastic means, and preferably the liner sheet is not joined to the absorbent core or backing layer for a region of about 8 mm to about 12 mm adjacent the first and second edges of the elastic means.
- the absorbent article may be substantially hourglass shaped, or substantially rectangular shaped, with the hourglass shape being a currently preferred embodiment.
- the liner sheet generally has first and second waist edges that are substantially parallel to a transverse axis of the article.
- the article also includes first and second side edges.
- the backing layer and the liner sheet define first and second leg openings.
- the elastic means may comprise at least a first elongate elastic band that is secured to the liner sheet.
- a first end portion of the first elongate elastic band is disposed adjacent the first waist edge and extends towards the second waist edge and between the longitudinal axis and the first side edge.
- the first elastic band has first and second edges, and in the crotch region the liner sheet is free of adhesive adjacent the first and second edges, so that the liner sheet is not bonded to the absorbent core or backing layer in the regions adjacent the elastic bands.
- the article also includes at least a second elongate elastic band that is secured to the liner sheet, and which has a first end portion disposed adjacent the first waist edge and between the longitudinal axis and the second side edge.
- the second elastic band has first and second edges as well, and the liner sheet also is free of adhesive adjacent the first and second edges.
- the region adjacent the first and second edges that is devoid of adhesive, and hence is not bonded to the absorbent core or backing layer, may vary. This distance generally is from about 5 mm to about 20 mm adjacent the first and second edges of the first and second elastic bands, and preferably from about 8 mm to about 12 mm.
- Both the first elongate elastic band and the second elongate elastic band are attached to both the liner sheet and backing sheet around the leg openings.
- the article also may include third and fourth elastic bands.
- the third elastic band is located adjacent the first waist edge and between the first waist edge and the transverse axis.
- the fourth elastic band is located adjacent the second waist edge and between the second waist edge and the transverse axis.
- the first-through-fourth elastic bands collectively define a pocket region in the crotch of the article for receiving exudates.
- the elastic bands collectively gather the liner sheet, separate from the backing sheet, to form the exudate pocket.
- both the hourglass- and rectangular-shaped absorbent articles also may utilize serpentine elastic bands.
- the liner sheet has first and second waist edges that are substantially parallel to a transverse axis of the article, and first and second side edges.
- the backing layer and the liner sheet define first and second leg openings.
- the elastic means comprise at least a first elongate elastic band that is secured to the liner sheet in the crotch regions of the article, and secured to both the liner sheet and backing sheet around the leg openings.
- a first end portion of the first elongate elastic band is disposed adjacent the first leg opening and between the first leg opening and the first waist edge, as well as between the longitudinal axis and the first side edge.
- the first elastic band extends in a curvilinear path around the first leg opening towards the second waist edge and crosses the longitudinal axis between the second waist edge and the transverse axis.
- the first elastic band extends in a curvilinear path around the second leg opening and towards the first waist edge. This elastic band then terminates at a second end portion adjacent the second leg opening and between the second leg opening and the first waist edge, as well as between the longitudinal axis and the second edge.
- the article also includes at least a second elongate elastic band that is secured only to the liner sheet in the crotch portions of the article, and to the liner sheet and backing sheet around the leg openings.
- the second elongate elastic band has a first end portion disposed adjacent the first leg opening and between the first leg opening and the second waist edge, as well as between the longitudinal axis and the first side edge.
- the second elastic band extends in a curvilinear path around the first leg opening towards the first waist edge and crosses the longitudinal axis between the first waist edge and the transverse axis.
- the second elastic band also extends around the second leg opening and towards the second waist edge.
- the second elastic band terminates at a second end portion which is adjacent the second leg opening and between the second leg opening and the second waist edge, as well as between the longitudinal axis and the second edge.
- This embodiment of the invention also may comprise plural first elongate elastic bands, and plural second elongate elastic bands.
- the plural first elastic bands and the plural second elastic bands define plural first and second elastic band edges.
- the liner sheet is substantially free of adhesive, and therefore is not bonded to the absorbent core or backing sheet from at least about 5 mm to about 20 mm, preferably from about 8 mm to about 12 mm, adjacent the edges of the elastic means.
- the absorbent garment is rectangular and includes serpentine elastic members
- the first and second waist edges are substantially parallel to a transverse axis of the article, and the first and second side edges also are substantially parallel to the longitudinal axis.
- the elastic means comprise at least a first elongate elastic band that is secured only to the liner sheet in the crotch region, and to the liner sheet and backing sheet adjacent the leg openings.
- a first end portion of the first elongate elastic band is disposed adjacent the first waist edge and between the longitudinal axis and the first side edge.
- the first elastic band extends in a curvilinear path towards the second waist edge and crosses the longitudinal axis between the second waist edge and the transverse axis.
- the elastic band thereafter extends towards the first waist edge and terminates at a second end portion adjacent the first waist edge and between the longitudinal axis and the second edge.
- This embodiment also includes at least a second elongate elastic band that is secured only to the liner sheet in the crotch region, and to the liner sheet and backing sheet adjacent the leg openings.
- the second elongate elastic band has a first end portion that is disposed adjacent the second waist edge and between the longitudinal axis and the first side edge.
- the second elastic band extends in a curvilinear path towards the first waist edge and crosses the longitudinal axis between the first waist edge and the transverse axis.
- the second elastic band thereafter extends towards the second waist edge and terminates at a second end portion that is adjacent the second waist edge and between the longitudinal axis and the second edge.
- the elastic bands collectively define a pocket in the crotch region of the diaper for receiving exudates by gathering the liner sheet, which is not attached to the core or backing sheet, independently of the backing sheet.
- the article also may utilize plural first and second elongate elastic members.
- the liner sheet of the article is substantially free of adhesive from at least about 5 mm to about 20 mm, preferably from about 8 mm to about 12 mm, adjacent the edges of the elastic members in the crotch region.
- a preferred embodiment of the invention comprises an absorbent article having first and second waist edges that are substantially parallel to a transverse axis of the article, and first and second side edges.
- the absorbent article includes a moisture-impervious backing layer, a liner sheet having a first major surface adapted to contact the wearer and a second major opposed surface, and an absorbent-core layer positioned between the liner sheet and the backing layer.
- the backing layer and the liner sheet define first and second leg openings.
- the absorbent article utilizes plural first and second elongate elastic members that are adhered to both the liner sheet and backing sheet to define leg gathers. In the crotch region, the plural elastic members are attached only to the liner sheet, and thereby form a containment pocket for containing exudates.
- the plural first elastic members have plural first end portions that are disposed adjacent the first leg opening and between the first leg opening and the first waist edge.
- the plural first elastic members also are disposed between the longitudinal axis and the first side edge.
- the plural first elastic members extend in a sinusoidal path around the first leg opening towards the second waist edge and cross the longitudinal axis between the second waist edge and the transverse axis.

- the plural second elastic members are disposed between the longitudinal axis of the article and the first side edge.
- the second elastic members extend in a sinusoidal path around the first leg opening towards the first waist edge and cross the longitudinal axis between the first waist edge and the transverse axis.
- the plural second elastic members extend in a sinusoidal path along the second side edge and terminate at plural second end portions adjacent the second leg opening and between the second leg opening and the first waist edge, as well as between the longitudinal axis and the second side edge.
- the first and second plural elastic members are disposed in substantially mirror-image sinusoidal paths and, in combination with the liner sheet, form a raised elasticized region of the liner sheet which defines a containment pocket in a crotch region of the article for receiving body exudates.
- the backing sheet and liner sheet are joined to each other at discrete locations by an adhesive to maintain the core therebetween.
- the plural first and second elastic members define plural first and second elastic member edges, the backing sheet and liner sheet being free of adhesive in the crotch region for about 5 mm to about 20 mm adjacent the plural first and second elastic member edges, preferably from about 8 mm to about 12 mm.
- This invention also provides a method for producing an absorbent garment.
- the method comprises providing at least a first elongate elastic member and at least a second elongate elastic member, an absorbent pad, a sheet of moisture-impervious backing-layer material, and a sheet of liner sheet material.
- the sheets of backing and liner sheet material each have opposed first and second waist edge regions and first and second side edges on opposite sides of the longitudinal axis of the sheet.
- the backing layer and the liner sheet also may define first and second leg openings.
- At least a singular first elastic member has a first end portion disposed adjacent the first leg opening and between the first leg opening and the first waist edge, as well as between the longitudinal axis and the first side edge.
- the first elastic member extends around the first leg opening in a curvilinear path towards the second waist edge and crosses the longitudinal axis between the second waist edge and the transverse axis.

- the illustrated embodiment has a substantially hourglass-shape as previously discussed in relation to FIGS. 2 and 5 and its general construction is similar to those described in relation to FIGS. 2 and 5.
- the elastic members designated here as 44d, 46d are dispersed in a different relationship than in prior embodiments.
- the liner sheet 12 includes a first waist edge 22d and a second waist edge 24d.
- the article 2 also includes a first leg opening region 30d and a second leg opening region 32d.
- the elastic members, or bands, 44d and 46d are secured only to the liner sheet 12 in the crotch region 38.
- a first end portion 48d of elastic member 44d is disposed adjacent side edge 26d between transverse axis 20 and waist edge 24d.
- the elastic member 44d extends in a curvilinear path around a portion of leg opening 30d and toward the other waist edge 22d between the longitudinal axis 18 and side edge 26d.

- elastic band 46d extends transversely of the article substantially parallel to axis 20, between axis 20 and waist edge 24d.
- the elastic band 46d has first and second end portions 52d, 54d, respectively, which are adjacent leg openings 30d, 32d respectively.
- Band 46d intersects band 44d adjacent leg openings 30d, 32d.
- Elastic bands 44 and 46 are secured to the liner sheet 12 by means known in the art, such as an adhesive.
- Liner sheet 12 is not attached to absorbent core 14 and backing sheet 10 in the region of the elastic bands in crotch region 38.
- An important aspect of the present invention is both the location and pattern of the elastic members, such as 44 and 46, as well as the bonding of the liner sheet 12 to the backing layer 10.
- Prior-art absorbent garments have formed pockets for receiving body exudates by removing a portion, such as an oval portion, from the liner sheet 12. This adds processing steps to the manufacture of the article 2, and also adds to the expense associated therewith.
- the present invention forms a pocket 68 for receiving body exudates, but does not require that the liner sheet 12 be processed to define a cut-out region.
- the pocket 68 may be formed by raised elasticized barrier means.
- raised elasticized barrier means refers to a liner sheet structure 12 that is free to separate from the absorbent core 14 and backing layer 10 in selected portions of crotch region 38. This can be accomplished, for instance, by providing a heat-activated elastic portion of the liner sheet 12. In such an article the liner sheet 12 may be elasticized by applying heat to sheet 12, such as by using heated rollers. Alternatively, the elasticized barrier means may be formed by securing elastic means, such as members 44 and 46, to the liner sheet 12.
- elastic members 44 and 46 along with having certain regions of the liner sheet 12 not joined to backing layer 10 and the absorbent core 14, collectively form the raised elasticized barrier region 70.
- the raised elasticized barrier region 70 is illustrated in FIGS. 1 and 7. Because the elastic members 44 and 46 are attached to the liner sheet 12, and because the liner sheet 12 is not bonded to absorbent core 14 or backing layer 10 at certain discrete regions, the liner sheet 12 is retracted separately from the backing layer 10 and absorbent core 14, thereby allowing for the subsequent formation of the pocket 68 and the raised region 70.
- the pocket area 68 which lies interiorly of band members 44 and 46, sags upon receiving body exudates. This allows the liner sheet 12 to provide a pocket 68 and a raised elasticized barrier region 70, which protects the user of the article 2 from exudate leaks and contact with the exudate.
- the elastic bands 44 and 46 include first opposed elastic band edges 56 and 58 and second opposed elastic band edges 60 and 62, respectively.
- the elastic members 44, 46, 64 and 66 are bonded directly to the liner sheet 12 in the crotch portion 38 at regions directly beneath the elastic members 44, 46, 64 and 66.
- the liner sheet 12 is not bonded to the backing layer 10 or to core 14. This region of nonbonding extends for approximately 5 mm to about 20 mm adjacent each edge of the elastic members 44 and 46, and preferably extends from about 8 mm to about 12 mm.
- the combination of the placement of the elastic members 44 and 46, along with leaving certain regions of liner sheet 12 not bonded to backing layer 10, allows for the raising or retraction of the liner sheet 12, and the subsequent formation of the elasticized barrier region 70.
- Elastic members 44, 46 typically are bonded to liner sheet 12 in a stretched or tensioned condition.
- the term "bonded” refers to adhesive bonding, sonic bonding, heat bonding, solid bonding, stitching or any other method of affixing the elastic members 44, 46 to the liner sheet 12.
- the elastic members may comprise any elastic member suitable for use with article 2, such as a natural rubber elastic that can be obtained from Fulflex, Inc., of Middletown, R.I. This material typically is stretched lengthwise prior to being affixed to liner sheet 12.
- other elastic materials also may be used, such as a heat-activated material, for example, a thermally activated elastic TAE from 3M Company.
- Other elastic materials which may be used to practice the present invention include natural rubber, polyurethane, ribbon elastic, lycra strands, or others used in the industry.
- FIGS. 8 and 9 A method and apparatus for producing an absorbent article 2 according to the invention are shown schematically in FIGS. 8 and 9. Initially, the backing layer 10 and pad 14 are assembled. An elongate web of backing layer 10 is drawn from a roll 100 (FIG. 9) in the direction of arrows 102 and 104. A spray device 106, having a swing-arm 107, places adhesive on selected portions of sheet web 100. Pad 14 is then positioned on top of backing material 10 by conveyor 109 moving in the direction of arrow 111.
- the liner sheet 12 is being produced. Initially, an elongate web of liner sheet material 12 is drawn from a roll 74 and carried in the direction of arrow 76. The bottom surface 42 of liner sheet 12 is sprayed with a pattern of adhesive as shown generally in dashed line in FIG. 8 by applicators such as 112 having a swing-arm 113.
- the adhesive pattern is substantially continuous along sheet 12 and has a width preferably no greater than the width of the pattern of the elastic members 44 and 46 to be applied thereto.
- Elastic members 44 and 46 are drawn from a reservoir indicated generally at 108 and are applied to liner sheet 12 through elastic applicators, such as applicator 115, which may be attached to oscillating arm 113. As a result, oscillating arms 113 can be used to apply both adhesive and elastic members 44, 46 in the same preselected pattern. Elastic members 44, 46 are applied to sheet 12 in a tensioned form. Elastic members 44, 46 may be placed on sheet 12 in overlapping sinusoidal curves, as illustrated in FIGS. 2 and 4, or may be placed in a substantially parallel relationship to the longitudinal transverse axis, as shown in FIGS. 5 and 6.
- the combined liner sheet 12, elastic members 44, 46, core 14, and backing sheet 10 are then adhered or joined to each other using, for example, an adhesive, sonic bonding or heat bonding. Any such bonding or adhering pattern used to join the component parts of the assembly must leave a region surrounding the elastic members in the crotch region free of the underlying backing sheet and core to permit the forming of the exudate-receiving pocket. However, the central crotch region of the liner sheet may be adhered to core 14 in regions spaced from the elastic members.
- swing-arm waterjet cutters such as that indicated generally at 98 in FIG. 9, may cut out the article 2, as well as any leg openings 30 and 32 that may be used, as illustrated in FIGS. 2 and 5.
- a final transverse knife, or cutter, (not shown) is operable to sever individual garments from the continuous flow product produced in the method just described.
